IMPROVEMENT IN WHEELS FOR VEHICLES.

Specification forming part of Letters Patent No. 157,390, dated December1, 1874; application filed September 25, 1874.

To all whom it may concern:

Be it known that I, HENRY GWYNN, of Baltimore city, in the State ofMaryland, have invented a new and Improved Wheel; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawing, forming apart of this specification, in which- Figure l is a side elevation ofthe hub with a portion broken away Fig. 2, a vertical section throughline 00 :0,- Fig. 3, detail, showing projections and flanges; Fig. 4,detai1,showing the tapering of the side walls of the socket.

This invention relates to certain improve ments upon the patent of HENRYGWYNN, No. 145,646, dated December 16, 1873. It consists in thecombination, with the spokes and other coacting parts, of asocket-plate, which is cast in one and the. same piece with the shell orhub, and provided with sockets, which have inclined bottoms and taperingsides, the said socket-plate being cast in one piece with the hub toprevent the revolving of the spokes upon the hub, and the sockets beingtapering laterally, and provided with inclined seats to tighten thespokes both laterally and longitudinally when screwed up by a nut andbindingplate.

In the drawing, A represents a metallic shell, tapering on the insidefrom the inner to the outer end, and having fitted within it a woodenjournaLbox, B, which is rigidly held to shell bymeans of the V-shapedflange attached to said shell. The shell A projects at the outer endover the nut that fastens the wheel to the axle, said nut bearingagainst the ends of the V-shaped flanges, as also against the woodenjournal-box. C is the socket-plate, which is cast with the shell A,

and in the construction of which lies the improvement which constitutesmy invention. Said plate is cast with sockets D, which are both widerand deeper at the front than at the back, the taper or incline of thebase of the socket being intended to tighten the spoke longitudinally,and the taper of the sides of said socket to tighten the spokelaterally. The spokes are made with their sides and ends inclined toadapt them to the peculiar shape of the sockets, and rest in the samebetween the triangular sections of metal E. F is an annular plate,provided with roughened surfaces a, which clutch the spokes and flangesb which pass between thei G is a screwthreaded nut, which meshes with ascrew thread upon the shell A, and forces plate F against the spokes.

' When the spokes are to be introduced their extremities are firstplaced in the sockets in the felly, and then the other extremity, withthe inclined end and sides, placed in the laterally-taperin g socket D.Now, when the nut forces the plate F, with its roughened sides againstthe spokes, the latter are tightened longitudinally by the inclined baseof the socket, and laterally by the inclined sides of the same.

By means of this arrangement I have a much simpler and more efi'ectivemode of fastening and adjusting the spokes, and one in which the cost ofmanufacture is duced.

Having thus described my invention, what I claim as new is-- Thecombination, with spokes having in- I clined ends and sides, plate F,and tap G, of a socket-plate, 0, cast in one piece with the shell A andthe triangular section E, forming sockets which are deepest and widestat the point where the spokes are introduced, substantially as and forthe purpose described.
